- be oscillated carrying with it' the ratchet,

sis

to which it"issecured. From the foregoing description', it will be to operate the shaft through the medium of the pawl and ratchet mechanism as any motion imparted to the casing in-one direction is transferred to the pawl and ratchet mechanism and internal gear portionof the-casing to the central hub member fixed upon the shaft to be driven. 1

The sections of the casingare with apertured ear-s19 through which a bolt 20 is adapted .toextend for firmly fastening the sections together, and it will be seen by this construction the sections can be readily secured together or separated so'as to reach the interior of the mechanism. Whenin use, the casing packed with grease so asto thoroughly lubricate the mechanism there in and to reduce the wear and noise when in operation.- 1 M It will be seen-that when the pawl and ratchet mechanism secured-on the end of a shaft, as shown in'l ig. 1, when the operating rod is given a pull, thecasing will wheel and through the medium of the gears of the ratchet wheel and gears of the casing, motion is imparted to the hub member through the medium ofthe pinions so as to cause the-hub member to osciliat'ethe shaft seen that I have provided a pawl and ratchet mechanism which is capable of being readily attached'to a shaft tobe intermittently rotated either direction, composed of a central hub member revolubly mounted within the asing and provided with oppositelydisposed pinio'ns meshing with the internal gear of the; casing and the gear'carried by a ratchet wheel whereby any motion which is transmitted to the outside can be closely gage'd and pra'ctically'any adjustment made up to at least one one-hundredth part of an inch.

What is claimed is: V

1. In a pawl and ratchet mechanism, a

shaft, a hub member fixed on said shaft provided with oppositely disposed arms, pinions carried by said arms, a ratchet wheel loosely mounted upon said'hub member provided with gear meshing with said pinions,a casi'ng inclosing said pinions, hub

' member and ratchet wheel and a gear carried by said casing meshing with said Pinions.

2. In a pawl and ratchet/mechanism, a

shaft,a hub member fixed on said shaft, a V ceasing loosely mounted on said hub member,

a ratchet wheel loosely mounted upon said hub member provided with a gear, oppositely disposed arms formed on said hub member, pinions carried by said arms meshing with said gear, a pawl-carried by said casing -coiiperating with said ratchet wheel and a gear formed on said casing cooperatmg with'said pinions;

provlded v 'pinion's. 1

3. In a pawl and ratchet mechanism, the combination with a shaft tb be rotated, of aihub member fixed on said shaft, a ratchet wheel l'ooselymounted upon said hub mem "ber provided with a gear, pinions carried bysaid hub member cooperating with said gear,' a casing inclosing said hub member and ratchet wheel, a pawl carried by -said casing. cooperating .Withsaid ratchet wheel, and a gear carried by said casing cotiperating with vsaid pinions. I

4c; fA pawl and ratchetmechanism, comprising a two-piece casing having registeringilips, a'pivoted spring actuated dog mounted in said lip, a ratchet wheel arranged within said casing cooperating withsaid dog, a gear formed centrally onsaid ratchet wheel, a hub member having a bearing for said ratchet wheel, arms extending outwardly from said hub member carrying pinions meshing with the gear of saidratchet wheel, and'a gear carried by one of the sections of said casing meshing with: said a: hub "member having notchesat its Lends arranged upon said shaft, keys carried by said shaft extending into said notches, said hub member being provided; with oppositely disposed arms carrying bearing'pinmpinand ratchet mechanism, the combination with aZsha-ft to be rotated, of:

ions loosely-mountedupon said bearing pins, a ratchet wheel loosely'mounted upon said hub member'havinga central gear meshing with 'sai'dpinions, a casing inclosing said hub member and ratchet wheel and mounted to oscillate upon saidhub member, adog' member carried by oneof the sectionsof ion's and a pivoted dog arranged within said casing cooperating with said ratchet wheel. I, Y p The' combination "of ashaftto be rotated,'of ah'ub member fixed on said shaft providedwith oppositely disposed arms'car rying pinions, a casing mounted to"oscilla'te upon said hub member, ,a dog carriedby said "casing, a' ratchet wheel revo'lubly mounted upon said hub membereng'aged carried by said casing meshing with said pinion s, said shaft "being locked to the case ing by said dog by themotion of the casing in one direction-and unlocked therefrom by y Said dog, a gear rr bysaid ratchet wheel meshing with said. pinions, a gear direction.

8. A pawl and ratchet mechanism, comprising a casing mounted to oscillate, a hub member fixed to a shaft upon which said casing is mounted, said hub member being provided with oppositely disposed arms, a ratchet wheel revolubly mounted upon said hub member having a central gear, pinions carried by said arm meshing with said gear, an internal gear formed in said casing meshing with said pinions, and a pivoted dog carried by said casing and cooperating with said ratchet wheel.

9. In a pawl and ratchet mechanism, the combination with a shaft to be rotated, of a member fixed on said shaft, pinions carried by said member, a ratchet wheel rotatable on said shaft, a gear carried by said ratchet wheel meshing with said pinions, a member oscillatable on said shaft having a gear meshing with said pinions, a dog carried by said oscillatable member cooperating with said ratchet wheel, said shaft being locked to said oscillatable member by said dog by the movement of said oscillatable member in one direction and unlocked therefrom by the movement of the oscillatable member in the opposite direction.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
